2-point Calibration Adjustment
Preferred method for very unusual substrate materials, shapes or
conditions. Provides greater accuracy within a limited, defined
range.
This method requires taking two readings at known thickness
values: a thin value (often zero) and a thicker value. These values
should be on either side of the thickness range to be measured.
1.Select 2 Pt Adjust from the Cal Settings menu.
2.Press (+) to select the number of readings to be used to obtain
an average on the thinner item, typically 3 to 10 readings. The
greater the variation between readings, the more readings
should be taken to obtain an average.
3.Repeatedly measure the thinner item. The Gage will wait for 2
seconds on the surface to allow the user to correctly position the
probe on the surface. After the last measurement the Gage will
calculate and display a thickness value which represents the
average of all the readings taken using the factory calibration
settings.
4.Lift the probe from the surface and adjust the displayed reading
down (-) or up (+) to the known thickness value of the thin item.
Press to accept this value.
5.Repeat steps 2 - 4 for the thicker item.
When selected, the icon will appear and all calibration settings
are “locked” to prevent further user adjustments.

Select Non-Ferrous Lock (N Lock) when operating regularly on
non-ferrous substrates. The icon will appear and the probe will
only use the eddy current principle when measuring. N Lock is
useful when measuring coatings on plated steel.
